Machine data: Kubota, operating weight, source: https://kuk.kubota-eu.com/constructionmachinery/wp-content/uploads/sites/4/2021/07/KUK-U50-5_U56-5_KX060-5-EN_2025.pdf. Equipment and year of build can differ.
Oil flow and pressure
Kubota publishes up to 65 l/min for the auxiliary circuit of the U50-5. The Promove XP300 needs 50–60 l/min, so the flow must be reduced to that range before use. We check this with your machine data before we send the written quote.
Mounting and adapter plate
The Promove XP300 has a bolted top plate 330 × 330 mm. A quick coupler or adapter plate for your U50-5 is quoted as a separate line when needed. Please send the coupler type or pin dimensions with your enquiry.
What to send us for a fit check
Send these details with your enquiry, and we check them against the datasheet:
- excavator make, model and operating weight,
- quick coupler type or pin dimensions,
- flow and pressure of the auxiliary hydraulic circuit,
- relief valve setting, and whether the return line goes directly to the tank,
- your company name and VAT number.
